Configure Authentication for Outlook Anywhere
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
You can use the EMC and the Shell to configure authentication for Outlook Anywhere.
The first time that you run the Enable Outlook Anywhere wizard in the EMC, you can select the authentication method that you want to use for Microsoft Office Outlook 2007, Outlook 2010, or Outlook 2003 clients. However, if you want to configure authentication and you've already run the Enable Outlook Anywhere wizard, you can use the Set-OutlookAnywhere cmdlet in the Shell.
When you specify authentication for Outlook Anywhere, you set the authentication method that will be used by the Outlook client. This authentication method is automatically provided to the client by the Autodiscover service. This authentication method is separate from the authentication method on the /rpc virtual directory that's located on your Microsoft Exchange Server 2010 Client Access servers. By default, the /rpc virtual directory is enabled for Basic authentication, and the authentication method can't be modified.
To choose the correct authentication method, see Understanding Security for Outlook Anywhere.
